ObjectiveThis study was designed to search for risk factors predicting mortality of patients with Wegener's granulomatosis (WG) treated on the intensive care unit (ICU).MethodsSeventeen patients admitted to the ICU of an University Hospital for an acute illness related to WG were analysed retrospectively over 4 years. A variety of clinical and laboratory variables were recorded. Contingency table analyses, univariate logistic regression, and discriminate analysis were performed to determine which factors influenced a negative outcome.ResultsReasons for ICU admission were respiratory failure (n = 10), severe haemoptysis (n = 13), sepsis (n = 9), acute renal failure (n = 6), and gastrointestinal bleeding (n = 1). Patients were treated for a median of 6 days (range 4-121 days). During the stay in the ICU, five patients died within 24-121 days (overall mortality 29.4%). Causes of death were cerebral haemorrhage (n = 2), pulmonary embolism (n = 1), and sepsis (n = 2). Significantly associated with death were: Acute Physiology and Chronic Health Evaluation II (APACHE II) score>24 [p = 0.004, odds ratio (OR) 0.568, 95% confidence interval (CI) 0.327-0.989], period of time in the ICU>10 days (p = 0.001, OR 0.795, 95% CI 0.589-1.072), and treatment with cyclophosphamide during the stay in the ICU (p = 0.013, OR 0.799, 95% CI 0.651-0.980). No association was found for higher age, C-reactive protein (CRP), pulmonary involvement, serum creatinine, and requirement of haemodialysis.ConclusionsThe prognosis for WG patients in the ICU is serious, but the majority can survive. To achieve a more favourable outcome, patients should stay in the ICU for as short a time as possible. The occurrence of renal failure did not influence the outcome in our patients.
